Results—Between May 1997 and December 2002, we recruited 549 cases of hemorrhagic stroke, of which 322 were
intracerebral hemorrhage and 227 were subarachnoid hemorrhage. Untreated hypertension was found to be a significant
risk factor for hemorrhagic stroke (odds ratio [OR]3.5 [2.3 to 5.2]; P0.0001) as was treated hypertension (OR1.4
[1.0 to 1.9]; P0.03). Insurance status of “self-pay” or Medicaid was a significant risk factor for untreated hypertension
(OR2.7 [1.6 to 4.4]). We estimate that 17% to 28% of hemorrhagic strokes among hypertensive patients would have
been prevented if they had been on hypertension treatment.
